I responded to a fire sprinkler system malfunction in Hillsboro, OR. The issue was caused by a faulty flow switch that wasn’t sending the correct signals to the control panel. I troubleshot the system, isolated the problem, and replaced the defective flow switch. I then tested the system to ensure proper operation, including checking the water pressure and verifying the functionality of the alarm system. After the repairs, the sprinkler system is now functioning correctly and ready for use.
